SADAKIGHI SATOW, OF SEND, JAE-All.

To all iokom it may concern:

Be. it known that I, Sammom SATOW, asubject' of the Emperor of Japan,. residing at- Sendai, Japan, ave made a certain new and useful Invention in Varnish and Process of i-i al the Same, of which the follow- .i -isaspecification. 0

- 's' invention relates to. varnlsh and method of making the same.

It is among the special purposes of my present invention to utilize vegetable groteids in the manufacture of varnish an to I thereby produce a varnish which possesses he The oil, solvent is The mass thus reduced, I will call many importantand valuable advantages over hitherto known varnishes. v

' It is also among the special purposes 0 my invention to provide a method of mak- I I V i1 c'ient,

In carrying out my. invention I employ, as raw material, any suitable material or substances containing vegetable proteids, such as leguminous 'or otherv vegetables, fgrain or the'lik'e. Examples of such raw material are beans, peas, wheat, corn and the likel.

The raw' material contain which is simple, economical and ar structure thereo and, if the material contains an undesira lepercentage of oil, the oil content of the crushed mass is removed, Flay be eifelcteg in any suitarlle mann or exampe y treating e with an oilsolvent such as benzln. then removed from the .meal or proteid inea and the proteidal suces contained therein are ac arated therefrom toproduce a refined protel prodso not. This separation of the roteidal substances from the proteid mea may be efs w in various ways. According to one method the meal is treated with an alkaea mastic 'or line solution, such asa dilute solution of carbonized alkali, or caustic or ca H- ammonia, and the proteidal submnces, either with or without further purification of the resulting liquid, are precip1 ta therefi'om. The further purification referred to may be accomplished mechanional precipitation, fractional soluticn of precipitated impure proteids, or by converting one or more components into Specification of Letters Patent.

ies which enable thei pro r separation; or one or more of these various purl methods may be employed in combination with the others, The precipitation of the refined proteidal substances is accomplished byadding a suitable acid, such as sulfuric, sulfurous, acetic or phosphoric acid, or by a suitable ferment, such as lactic or acetic.

According to another method the meal is treated with water and the refined proteidal products are precipitated out ofthe resultmg liquid, either with or without purification thereof, as above e lained, the precipitation being efiected wit an acid or a ferment as above described. N

According. ,to still another method the. meal is treated with an eous salt solution, such as sodium chlori ammonium sulfate, or the like, and the resulting liquid either with or without. further purification as explained, is subjected to dial sis. The proteidal substances 0 tained as above described are suitablea (1 highly eflicient for use in making v in accordance with my invention. a Be In the preparation of the varnish the proteidal' su stances, obtained as above described, are kneaded with a suitable glutinizing agent to produce a very viscid semitranspa'rent stic fluid. Various lutinizing agents may employed for this purpom, either basic oracldic- I have found that among the basicagents suitable for th purpose the following ma be used; p .(a) Caustic alkali, see as caustic soda or otash; carbonated alkali, such as sodium car u nuts, or potassium carbonate; or. am-. monia or ammonium carbonate; or caustic (6) Alkaline salts such asborax, sodium 0s phosphate, and the like, having the property of alkaline in eons solution.-fin c amc bases,'suc as urea, pyrl I glycin, and other basic amino compoundg or the like. 1W

Among the acidic agents suitable for use in carrying out my invention I have found thatlthe following can be used with excellent (d) nic acids of the fatty acid seme ries, suc as formic, acetic, pro ionic,

phenyl-propionic, malonic and the e. (e) Organic'acids 0f the oxy-fatty series such as lactic, tartaric, citric, malic and the no I infectant.

, 7 thusobtained consists o fectant should also be added to prevent fermentation, and that every small percentage .ofphenol, salicylic acid, or creosote willanswer tins pun-pom. In this case the phenol or other agent acts only as adie- The. viseid mi-n-ansparent sticky fluid a whitish emulsified solution of gelatinized proteinfderiva-q tives and when applied as'a surface coating or varnish tor wow, metal or the like it forms, when dry, a hard colorless and transconsists in glutlnlzmg-vegetablc prote1ds ."with sulturous, acid: f r

active methylene compound, such as formal' dehyde, or the like, is added to the lutnuzcd roteidal liquid, or to the mass, w ile Encoded with a glutinizing' agent, as above described; Though the glutinized proteids condense rapidly under. ordinary conditions when treated with a condensing agent, the

presence of an excess'of water greatly .re

tards condensation to such an-extent that" condensation doesnot appear to take place;

Therefore,byvaryingthe amount of water 1" I which consists in glutmizmg vegetable pro-- I p .gtelds' and condensing the glutmized. mass linfi't e quality of the varnish product at .w1..

It is colorless and transparent and consequently, when-iapplied'to wood or other surfaces it ,does not produce ayellowish or brownish color '.which characteristic of-common I resin, but leaves the natural color and shades of. the a substance, .wood, or the like, .to-the surface of which varnish, employing the varnish is applied; It l'flqllll res no special skill in applying the varnis and it dries.
